RIng Sizer, works great! It even came with a free $10 gift card Great Value

perfect fit before buying the OURA ring - good invest

Excellent way to know which is the appropriate size and which one I feel comfortable with.

The product was helpful in deciding what size to get. I also used the sizer and pretended it was the real thing to see if id get uncomfortable wearing it since I dont wear jewelry often. I also wore it to see how well id keep track of the real thing once I get it.

Oura ring sizing kit was necessary to decide on the appropriate ring size as this size varies from normal sizing.

Good idea to get the right size ring — would be nice to offer a refund if you end up buying a ring.

This is Great to find out ring sizes that anyone who needs to buy a ring for any occasion.

This was awesome in helping my wife find the right fit for her Oura ring! Plus now we can share it with friends and family to help cut down on plastic waste!

If you are planing on getting the Oura use the zing kit and try it for a few days o see what works before buying the actual product

Oura ring sizing is NOT ACCURATE AT ALL! I cannot express how important this ring sizing kit is to purchase prior to buying an Oura ring.

Love, love, love! If you want to take a deep dive into how your nutrition, stress, and habits affect your rest, get this! One you know better, you do better!

I’m glad I got the kit because I was almost certainly going to get an Oura ring until I tried one of these on. I’m relieved I didn’t spend $500 on a bulky ring that I would’ve hated wearing.

Ring sizer is easy to use and worked for me. Definitely worth testing out a prototype ring before making a purchase

They are pieces of plastic that replicate what each ring size would feel like. I found it very helpful because no variation was comfortable for me and I learned the Oura is not for me.

I bought this to get the sizing for the Oura ring. Was nice to get a $10 Best Buy reward for this item and ended up using it towards a ring. I wore the sizer for several days to make sure it fit without ever getting too tight or too loose.

Very good and accurate ring guide was very useful in picking the oura ring, since they tell you to wear it on your index finger, it a much different size than the ring finger for us.

If your worried the device won't fit they send a whole box of plastic rings to try out. For plastic rings pretty good quality.

A must before buying an Oura ring but it’s not exactly the same as an Oura (I had to exchange my Oura ring for a size smaller when the ring I bought would fall off my finger when my hands were wet (same size from the sizing kit had no issues).

Highly will recommend getting this before purchasing the real deal that way it saves you the hassle of returning it and you will have the felling on how it feels on your finger

The sizing rings did exactly what they're supposed to do - I wore mine for about 48 hours to make sure my ring finger sizing didn't fluctuate too much during the day vs. sleeping hours. Gives you a solid idea of the thickness and shape of the Oura ring.
